Consensus? What Consensus?

London, 2 September: In recent weeks US President Obama and the UK’s Energy and Climate Secretary Ed Davey have both cited a survey of climate science abstracts that alleges an overwhelming consensus on the subject of global warming.

In a new briefing note published by the Global Warming Policy Foundation today, Andrew Montford reviews the methodology used in the survey and concludes that the consensus revealed by the paper by Cook et al. is so broad that it incorporates the views of most prominent climate sceptics.

“The consensus as described by the survey is virtually meaningless and tells us nothing about the current state of scientific opinion beyond the trivial observation that carbon dioxide is a greenhouse gas and that human activities have warmed the planet to some unspecified extent,” Andrew Montford says.

“The survey methodology therefore fails to address the key points that are in dispute in the global warming debate,” Montford adds.
